Conteúdo: | Effectiveness of a plant-shake method of sampling soybean Lepidoptera was evaluated. Laboratory-reared larvae were hand-infested and allowed to feed on the plants for 15 min or 24 h, depending upon the test. About 50% of introduced small larvae would be recovered on the dropcloth from pod-set to pod-fill and a ca. 60% at the green bean stage; ca. 66% of medium and large larvae would be recovered from pod-set to pod-fill and ca. 75% at the green bean stage. About 4-5% more Anticarsia gemmatalis Hubner of Heliothis zea (Boddie) than Pseudoplusia includens (Walker) were recovered. One sampler recovered ca. 8% more larvae than another. Calibration ratios for the plant-shake method are presented.
